Visual Inspection and Pre-checks
- Verify the BJB fuse 19 (30A).
- Verify the BCM fuse 3 (15A).
- Verify the BCM fuse 3 (15A).
- A1 PERFORM INSPECTION AND VERIFICATIONNOTE: Make sure battery voltage is greater than 12.2 volts prior to and during this pinpoint test.NOTE: If it is necessary to leave the battery charger connected during testing, do not leave it on its highest or boost setting. The highest settings can exceed 16 volts, resulting in false test results and setting of Diagnostic Trouble Codes (DTCs).

Did the ignition switch pass the component test?
Yes REPAIR circuit CDC35 (BU/WH) for an open. No INSTALL a new ignition switch. REFER to: Ignition Switch . - A6 CHECK THE PCM (POWERTRAIN CONTROL MODULE) TR PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, while viewing the PCMPID TR, place the gear selector in PARK and then NEUTRAL.
Does the PCMPID TR read YES in both positions?
Yes GO to A7 No DIAGNOSE the TR sensor, REFER to: Diagnostic Trouble Code (DTC) Charts and Pinpoint Tests - 3.5L EcoBoost (235kW/320PS) . - A7 CHECK THE STARTER RELAY CONTROL OPERATIONNOTE: The following step uses a test light to simulate normal circuit loads. Use only the test light recommended in the Special Tools table at the beginning of this article. To avoid connector terminal damage, use the Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test light probe directly on any connector.
- Remove the BJB starter relay.
- Measure:
Positive Lead Measurement / Action Negative Lead
BJB starter relay pin 1
BJB starter relay pin 2
- Make sure the transmission is in PARK or NEUTRAL.
- With the key in the START position, observe the test light.
Does the test light illuminate when the key is in the START position?
Yes GO to A8 No GO to A15 - A8 CHECK THE VOLTAGE TO THE STARTER RELAY
Is the voltage greater than 11 volts?
Yes GO to A9 No VERIFY BJB fuse 19 (30A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short. - A9 CHECK THE STARTER MOTOR OPERATION AT THE STARTER RELAY
- Ignition OFF.
- With the transmission in PARK or NEUTRAL, momentarily connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead
BJB starter relay pin 3
BJB starter relay pin 5
Did the starter engage and the engine crank?
Yes INSTALL a new starter relay. No GO to A10 - A10 CHECK THE BATTERY GROUND CABLE
Are the voltages greater than 11 volts?
Yes GO to A11 No CLEAN or INSTALL a new negative battery cable as necessary. - A11 CHECK THE STARTER MOTOR GROUND
Is the voltage greater than 11 volts?
Yes GO to A12 No CLEAN the starter motor mounting flange and MAKE SURE the starter motor is correctly mounted. - A12 CHECK THE VOLTAGE TO THE STARTER MOTOR
- Measure:
Positive Lead Measurement / Action Negative Lead C1716A-1 Ground
Is the voltage greater than 11 volts?
Yes GO to A13 No CLEAN the high current BJB connection to the battery post. CLEAN or REPAIR a positive battery cable as necessary. - Measure:
- A13 CHECK THE STARTER MOTOR FOR CORRECT OPERATION
- Ignition OFF.
- Connect a remote starter switch between the starter solenoid C1716A-1 ("B" terminal) and C1716B-1 ("S" terminal).
- With the transmission in PARK or NEUTRAL, momentarily engage the starter.
Did the starter engage and the engine crank?
Yes GO to A14 No INSTALL a new starter, REFER to: Starter Motor . - A14 CHECK FOR START INPUT AT THE STARTER
- Connect BJB starter relay.
